CHECKRElN-HOOK.

SPECIFICATION forming part of Letters Patent No. 555,444, dated February25, 1896.

A li ti fil d April 8, 1895. Serial No. 544,857. (No model.)

To aZZ whom it may concern.-

Be it known that I, HARRY F. HARTWELL, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Oheckrein-Hooks, of which the followingis a specification.

My invention relates to a new and useful improvement in checkrein-hooks,and has for its object to produce such a device that will effectuallyprevent accidental displacement or detachment of the checkrein from thehook or holder; and with this end in view it consists in certain detailsof construction and combination of elements hereinafter set forth andthen specifically designated by the claim.

In order that those skilled in the art to which my invention appertainsmay understand how to make and use the same, I will describe itsconstruction and operation in detail, referring by numbers to theaccompanying drawings, forming a part of this specification, and inwhich Figure 1 is a sectional elevation of my device in connection witha harness-saddle. Fig. 2 is a perspective of the same.

Similar numbers denote like parts in both views of the drawings.

1 is the ordinary harness-saddle, and 2 the body of the hook, attachedto said saddle in any well-known manner, and extending upward andbackward and terminating in the projection 3.

4 is a fiat spring, secured to the body 2 by the screws 5, and curvesupward and is provided with an opening 6, adapted to fit over theprojection 3; so that it will be seen that to insert the closed end of arein within the hook it is only necessary to exert sufficient pressureagainst the upper end of said spring, whereby it will be forced backwardand said rein permitted to pass within the inclosure of the hook, and asthe draft on said rein is always approximately forward it will not bepossible for it to become accidentally disengaged from said hook; butwhen it is desired to release it therefrom a sufficient pressure isbrought to bear upon the spring 4 to force it backward, when the reinmaybe Withdrawn from the hook. By the spring passing over the projection3 the rein is prevented from being withdrawn from the hook by a suddenupward jerk, often occasioned by the movement of the horses head.

I do not wish to be understood as limiting myself to the exact form ofhook and spring shown, as they may be modified within the limits of myinvention without departing from the spirit t hereof.-

What I claim as new and useful is As an article of manufacture, thehereindescribed oheckrein-hook consisting of the bent hook 2, the saddle1, the spring-strip 4 with an opening 6, and a shouldered projection 3on said hook adapted to enter the opening 6, as and for the purposedescribed.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.

HARRY F. I-IARTW'ELL.
